英文摘要	The large-scale high-intensity homogeneous magnetic field is an important resource to perform magnetic immunity tests for large scientific facilities. Generally, a multi-coil system with large cross-sectional area is used to generate the required test field, which has high power loss and conductor mass. In this article, we propose a novel method that introduces magnetically shielded room (MSR) to enhance the coil magnetic field and reduce power loss. The analytical model of the coil system based on MSR is established through the multi-reflection image method. In addition, the multi-objective optimization model is brought forward based on the non-dominated sorting genetic algorithm (NSGA-II). Theoretical results indicate that the magnetic field can be significantly enhanced under the presence of MSR. Consequently, prominent reductions in total current by about 61.4% and in total power loss by 75.5%-81.7% are achieved. Finally, the effectiveness of the theoretical result is numerically verified by the finite-element analysis (FEA). The proposed method provides a novel and promising way to reduce the power loss and conductor mass of such high-intensity magnet systems and other similar applications.
